[Pharo-users] Matching block parameter in rewrite rule

Hi, I was wondering if it was possible with the parse tree rewriter to match a block parameter? I would like to be able, for example, to rewrite: `#() detect: #odd ifFound: [ :e | e ] ifNone: [ self toto ]` as `#() detect: #odd ifNone: [ self toto ]` But I don't know how to express this rule with the rewrite rules of Pharo. I tried multiple things such as: '`@receiver detect: `@arg1 ifFound: [ `@arg2 | `@arg2 ] ifNone: `@arg3 ' -> '`@receiver detect: `@arg1 ifNone: `@arg3' or '`@receiver detect: `@arg1 ifFound: [ :`@arg2 | `@arg2 ] ifNone: `@arg3 ' -> '`@receiver detect: `@arg1 ifNone: `@arg3' Without sucess. Is there a way to do that or is it a limitation of the rewrite syntax? -- Cyril Ferlicot https://ferlicot.fr
